Problems solved by technology

However, after careful analysis, this scheme also has a fly in the ointment. The fasteners are connected by mutual insertion, which requires the pile body to accurately locate the position between each fastener when connecting each other. The connection between the two piles can only be realized when the positions are in one-to-one correspondence. Therefore, the docking process takes a long time to realize

Embodiment 1

[0040] Such as figure 1 As shown, a prefabricated pile with a locking end plate includes a strip-shaped pile body 10, a steel reinforcement cage 11 is arranged inside the pile body 10, and the two ends of the reinforcement cage 11 are thickened to form a pier head 111, so The pile body 10 described includes alternately arranged large section piles 12 and small section piles 13, the cross section shapes of the large section piles 12 and the small section piles 13 can be circular, square or other shapes, and the large section piles 12 and the small section piles The cross-sectional shapes of the piles 13 may be the same or different.

[0041] A locking end plate 20 is respectively fixed at the two ends of the pile body 10. The end of the pile body 10 can be a large-section pile 12 or a small-section pile 13. The shape of the locking end plate 20 is consistent with that of the pile body 10 ends. same shape as Image 6 As shown, the locking end plate 20 is circular, such as Fi...

Embodiment 2

[0053] The structure and connection method of this embodiment are basically the same as that of Embodiment 1, the difference is that, as figure 2 As shown, the locking groove structure 30 includes a groove 31 provided on the outer wall of the locking end plate 20 . That is, the locking end plate 20 is directly connected to the pile body 10 .

Abstract

The invention belongs to the technical field of precast parts in the construction industry and relates to a precast pile with locking end boards and a connecting method of the precast pile. A variable-section pile comprises a strip-shaped pile body. A steel reinforcement cage is arranged in the pile body. The two ends of the pile body are each fixedly provided with one locking end board. Locking groove structures are arranged on the outer walls of the locking end boards. The locking end boards are provided with stretching hole structures penetrating the locking end boards. Pier heads of the steel reinforcement cage in the pile body can be inserted in the stretching hole structures and clamped by the stretching hole structures. The connecting method includes the steps that the ends of two pile bodies are close, locking blocks are inserted in the locking groove structures of the locking end boards of the two pile bodies respectively, the shape and the size of the locking blocks inserted in the locking groove structures are matched with those of the locking groove structures, and a relative locking bolt is used for screwing and locking the locking blocks in the two locking end boards. The precast pile has the beneficial effects of being fast to connect, firm, easy to operate and the like.

Description

technical field [0001] The invention belongs to the technical field of prefabricated parts in the construction industry, and relates to a conveniently connected pile and a connecting method thereof, in particular to a prefabricated pile with a locking end plate and a connecting method thereof. Background technique [0002] Due to the relatively poor quality stability of immersed tube piles, prefabricated prestressed concrete piles have developed rapidly in recent years. In the piling process, piles of different lengths should be selected according to different needs, which requires the piles to be connected to each other to form a longer pile body. [0003] The existing piles are connected by setting metal end plates at both ends of the piles. When two piles need to be connected, they are connected by welding the end plates of the two piles. The welding work is time-consuming and laborious, and the connection is inconvenient , In addition, the weld is easily corroded by the...
